After an outbreak of vesicular stomatitis in July, the disease is on the decline in Northern Colorado. While Larimer County still has 36 facilities under quarantine, the number has dropped from 310 facilities in the state being in quarantine to only 96 by Oct. 1.

The virus affects cows, horses, pigs and other animals. It is rarely passed to humans, Ryan Maye reported for the Coloradoan. Veterinarians at Colorado State University think the virus will be mostly killed off by the first frost or snow.

While there are no vaccines that have been approved to treat the virus, the disease isn't necessarily life threatening to the animals. It causes sores and blisters in the animals' mouths, which can make it hard for them to eat or drink, however.
